Description
Technical field
The present invention relates to a kind of device of eliminating surface particles, be specifically related to a kind of device of eliminating the aluminium material surface particles that aluminium material extruder squeezes out, belong to control technology field.
Background technology
In aluminium material extruder, mold temperature is directly connected to the quality of aluminium product, along with the mold work time is more and more longer and friction mechanism effect, the operating temperature of mould can raise, cause aluminium product surface to have the oxide of more black particle shape, affect product appearance quality, this needs a kind of effective ways to make mould continuous firing in reasonable temperature interval.
Existing thermometry is a lot, by metering system, conventionally can be divided into contact and contactless two kinds.The feature of contacting temperature measurement method is that temperature element directly contacts measurand, carries out sufficient heat exchange between the two, finally reaches thermal balance, and at this moment the value of a certain physical parameter of temperature-sensing element and the temperature value of measurand exist a kind of definite functional relation.This temp measuring method advantage is intuitive and reliable, and shortcoming is the distribution that temperature-sensing element affects dut temperature field, and loose contact etc. also can bring measure error; The feature of non-contact thermometry is that temperature-sensing element does not directly contact with measurand, but carries out heat exchange by radiation, and non-contact thermometry thermal inertia is little, can reach signa, is convenient to measure temperature or the fast-changing temperature of moving object.But due to the impact to other media such as the distance between measurement mechanism and flue dust, steam of the emissivity, measurand that are subject to object, the temperature measurement error fluctuation of this temp measuring method is larger, and difficult demarcation.The temperature-measuring module of this design selects K type thermocouple temperature sensor as temperature-sensing element, 0 ℃～1000 ℃ of measurement categorys.K type thermocouple temperature sensor is the temperature sensor being widely used in industrial production, and it has, and certainty of measurement is high, measurement category is wide, simple structure and the advantage such as easy to use.
Existing temperature-controlled process also has a lot, general using high-low temperature difference makes it reach the object of cooling by thermal energy transmission, for example, liquid nitrogen temperature is lower, contact with high temperature die-cushion (200 ℃～300 ℃), make its cooling-down effect more obvious, and non-oxidative impurity, aluminium product is had no side effect, but cost is higher; Compressed air temperature is normal temperature, also has very large temperature difference with high temperature die-cushion, can reach equally the object of cooling, and cost is low, but has impurity.
